Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

This kind of ‘magic’ could lead to a computer revolution.

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth curvature of spacetime, the other the jittery statistics of particles and ...
